Edit
British battlecruiser, originally intended merely an improved Queen Mary class (herself a half-sister of the Lion class), so many alterations were made during the design phase that she ended up as a class of her own. Contain a much better turret layout and heavier secondary battery. Legend* has it that it is her that formed the basis of the Kongou design. Fought at Dogger Bank and Jutland. Broken up in 1932 due to further restrictions from the London Naval Treaty.
